"Immortal Master Xia, what is the important matter of summoning the lower officials here?"

In the afternoon, the autumn breeze blowing from the northern grasslands carried a slight breeze over this already yellowed hill.

Tang Bing wore the thin leather jacket that had been striking iron all the year round, held an iron hammer in his hand, and panted slightly under the leadership of the two soldiers to the back mountain of the military camp at Yatouguan.

Seeing the hammer in Tang Bing's hand and his rapidly undulating chest in front of him, Xia guessed that Tang Bing should have been still fighting weapons when he got the news of the soldiers, and as soon as he heard the news, he didn't even let go of the hammer and ran over directly.

"Uh...... Why don't you take a break first? Summer said.

Hearing this, Tang Bing was stunned for a moment, then hurriedly shook his head and said: "Military affairs are important, Xia Xianshi, you can say it, if there is anything to use my old Tang, my old Tang will definitely do his best!" ”

Seeing that Old Tang said this, Xia nodded, "Actually, I came to you this time to discuss important matters, and the stakes are very high, and this matter is impossible to achieve without you." ”

"Even this plan may be related to whether our Great Qin can completely expel and exterminate the Xiongnu in the future!"

Hearing this, Tang Bing's expression changed slightly, what kind of plan can eradicate the "ringworm" of the Xiongnu, which is as strong as Great Qin?

You must know that the Xiongnu and Donghu, the two big nomadic peoples, have been entrenched in the northern part of the Central Plains since the beginning of history, and since the Spring and Autumn Period, the Warring States have experienced an unknown number of overlords, and the emperor has not been able to expel these large and small nomads.

Otherwise, even the countries of Yan, Zhao, and Qin would not have built the Great Wall to defend against these foreign enemies hundreds of years ago.

And now that he heard that the mysterious plan in Summer's mouth could actually expel and exterminate these nomads, how could Tang Bing not be surprised.

If someone else said this, Tang Bing would definitely scoff at it, but at this moment, it would be completely different in the mouth of the summer, who had already deeply established the living immortals.

"No...... I wonder what role the lower officials can play? ”

Thinking that Xia said that without himself, this plan would not be implemented, Tang Bing suddenly felt a little panic in his heart, and there was a little joy and pride in the panic.

"You don't have to be nervous just yet." Seeing Tang Bing's somewhat trembling tone, Xia waved his hand.

"That's right, my so-called plan is to work with you to create weapons that can summon "Thunderfa", and then equip them in the hands of every soldier, and improve the combat effectiveness of our army through these weapons. ”

"Rayfa?" Tang Bing looked at Summer suspiciously.

"I don't know if you saw the explosion on the day of the Huns' attack?" Summer asked.

"Of course I did!"

Tang Bing nodded hurriedly, the scene that the explosion that day blew up nearly 100,000 Huns like headless flies left a deep impression on him, and it was by that mysterious explosion that the foundation for the victory was laid.

"Excuse me?" seemed to think of Tang Bing looking at Xia with surprised eyes, and said uncertainly: "No, no, the sudden explosion that day is the kind of weapon that can produce thunder as you said, Xia Xianshi!" ”

"That's right." Xia looked at Tang Bing's eyes and nodded lightly.

"No, it can't be......"

Looking at Xia's serious eyes, Tang Bing, who had received a definite answer, suddenly had all kinds of complicated emotions in his heart.

Tang Bing couldn't believe that the kind of explosion like Tianwei could actually be made, he was shocked that he personally got the news from Xia's mouth, he was happy that the limit of his pursuit of weapon power could be improved again, and the sadness was that he clearly knew how vulnerable the divine weapons he created in front of these Tianwei,

For a while, all kinds of emotions came to his heart, and the hammer that he had been holding firmly almost slipped in Tang Bing's hands.

Sensing the change in Tang Bing's face, combined with the impossible language before, Xia thought that Tang Bing didn't believe it.

So, Summer spent some Wish Power points to exchange a grenade directly from the exchange shop.

After the grenade appeared in his hand, Summer directly opened the safety bolt of the grenade, pulled the pull ring and threw it towards the large exposed rock in front of him.

“BOMM！”

A thunderous sound exploded directly in front of Tang Bing, and the wind from the explosion mixed with a little sand made his face hurt.

And Summer was prepared in advance, holding his broken small round shield of stainless steel in front of him.

"Now believe it, right?" Xia took a grenade and put it in front of Tang Bing, turned back to him and said.

Tang Bing was shocked by this loud noise, and then looked at the power caused by the grenade, and set off a large crater on the ground not far away, and the stones of a half-size person near it were blown apart.

Although such a power was not as powerful as the detonator explosives exchanged for system fragments used in the Hun attack at that time, the power of the explosion still made Tang Bing swallow his mouth when he felt the power of the explosion so closely.

"This, this is the weapon that can summon the "Thunder Law"? ”

Looking at the big pit not far away, and then looking at the fist-sized thing like an iron ball lying quietly in Xia's hand now, Tang Bing really had a hard time connecting the two.

"You try." Summer smiled and handed over the grenade in his hand.

It's better to explain it a hundred times than to let him experience it for himself.

Summer can understand that in this era before the invention of gunpowder, the power of commonly used weapons such as swords, guns, swords, and halberds is deeply rooted in the hearts of the people.

But it also limited their understanding of the power of gunpowder, a somewhat oversized "weapon" in this era.

Even Tang Bing, who had already created various divine blades, had the same cognitive limitations.

Tang Bing slowly stretched out his hand to take the grenade in Xia's hand, clenched the grenade tightly for fear that it would fall to the ground, and then worried that it would be too hard.

The slight pressure that inexplicably rose in his heart made his intention that had calmed down gradually become rapid again.

"Don't be nervous, take it easy." Seeing Tang Bing's nervous appearance, Xia patted him on the shoulder and began to guide him.

"Look at the pile of rubble in the distance, pull the tab off the grenade, and quickly throw it out of the spot you see."

Tang Bing looked at Xiaxia, then at the pile of rubble in the distance, and after a few consecutive glances, he forcibly suppressed the pressure in his heart and pulled out the ring of the grenade according to the steps Xia said.

Then he used the huge force that he had never used in his life to strike iron, and threw the grenade in his hand directly.

The grenade was thrown out by Tang Bing as if it had turned into an arrow, and flew directly over the pile of rubble that Xia said and crashed into the hill behind the rocky pile.

“BOMM！”

As soon as it hit the rock grenade, it exploded, and a huge fireball rose with a loud bang.

The rocks on the hill were blasted out of a large crater, and the crater on the rock wall was accompanied by small cracks like spider webs.

Then the rock wall began to become unstable, and the rubble continued to peel off from above, starting as small stones, and gradually turning into stones and large stones.

"Boom!"

After a while, the entire rock wall collapsed and smashed into the pile of rubble below, raising dust in the sky.

"This, this, this is me, I did it?"

Seeing that the stone mountain used for quarrying in the distance collapsed more than half of the rock wall directly due to his own reasons, Tang Bing was a little at a loss.

"See, explosions are art......"

Summer nodded, half-jokingly saying a well-known sentence from a certain ninja in his previous life, answering the Qin Dynasty man in front of him who had experienced overheated weapons.
